Charging and storing batteries
All battery types discharge over time when they are not being used. Batteries also
discharge faster in colder temperatures. If a Lithium Polymer battery is to be stored for
long periods of time, make sure it is fully charged before storing and re-charged at least
once every three months.

WARNING – Charge and use the rechargeable Lithium Polymer battery only in strict
accordance with the instructions. Charging or using the battery in unauthorized
equipment can cause an explosion or fire, and can result in personal injury and/or
equipment damage.
To prevent injury or damage:
– Do not charge or use the battery if it appears to be damaged or leaking.
– Charge the Lithium Polymer battery only with a product that is specified to charge it. Be
sure to follow all instructions that are provided with the battery charger.
– Discontinue charging a battery that gives off extreme heat or a burning odor.
– Use the battery only in equipment that is specified to use it.
– Use the battery only for its intended use and according to the instructions in the product
documentation.
Charging the internal battery
The internal Lithium Polymer battery in the rover receiver is supplied partially
charged. Charge the battery completely before using it for the first time. If the battery
has been stored for longer than six months, charge it before use.
To protect the battery from deep discharge, the receiver switches batteries or stops
drawing power when the battery pack discharges to 4 V.
A battery that has reached the deep discharge level cannot be recharged and must be
replaced. The following recommendations provide optimal performance and extend
the life of your batteries:
•
Fully charge all new batteries prior to use.
•
Do not allow the batteries to discharge below 4 V.
•
Keep all batteries on continuous charge when not in use. Batteries may be kept
on charge indefinitely without damage to the receiver or batteries.
•
Do not store batteries in the receiver or external charger unless power is applied.
•
If you must store the batteries, fully charge them before storing and then
recharge them at least every three months.

Disposing of the rechargeable battery
